1. A method for shaping a torque profile for a motor of a vehicle, the method comprising:
during a vehicle launch, an off condition of an engine, and upon receiving an engine start request,
predicting a time of engine engagement;
predicting a driver requested torque at the engine engagement; and
reducing a response of the motor to the driver requested torque until the predicted time of engine engagement based on the predicted driver requested torque at the engine engagement to shape the torque profile, wherein reducing the response of the motor to the driver requested torque based on the predicted driver requested torque at the engine engagement includes a percent reduction that ramps up and then down.
